Ingredients (Serves 4):
For the Burgers:
- 1 lb (450g) ground beef
- 1 tsp Worcestershire sauce
- 1 tsp garlic powder
- Salt and freshly ground black pepper, to taste
- 4 slices Swiss cheese
For the Foil Pack Toppings:
- 1 ½ cups sliced mushrooms (white or cremini)
- ½ small red onion, thinly sliced
For the Garlic Herb Potatoes:
- 1 lb (450g) baby potatoes, halved
- 1 tbsp olive oil
- 1 tsp Italian seasoning
- Salt and pepper, to taste
- 1 tbsp butter (optional – adds richness and shine)
Other:
- Non-stick cooking spray or oil for foil
- Heavy-duty aluminum foil (4 large squares)
Instructions:
1. Preheat the Heat Source
Preheat your grill to medium-high heat or your oven to 400°F (200°C).
2. Prepare the Burger Patties
In a mixing bowl, combine ground beef with Worcestershire sauce, garlic powder, salt, and pepper. Mix until just combined (don’t overmix), then form into 4 equal burger patties.
3. Season the Potatoes
In a separate bowl, toss the halved baby potatoes with olive oil, Italian seasoning, salt, and pepper until well coated.
4. Assemble the Foil Packets
Cut four large squares of foil (about 12×12 inches each). Lightly spray each square with non-stick spray.
On each piece of foil:
- Place a portion of seasoned potatoes in the center.
- Set a raw burger patty on top.
- Top with sliced mushrooms and red onions.
Fold the foil over the ingredients, sealing the edges tightly to create a packet. Make sure there’s enough space inside for air and steam.
5. Cook the Packets
- Grill Method: Place foil packets directly on the grill. Cook for 25–30 minutes, flipping halfway through if needed.
- Oven Method: Arrange packets on a baking sheet. Bake for 30 minutes, or until potatoes are fork-tender and burgers are fully cooked (internal temp of 160°F or 71°C).
6. Add the Cheese
Once cooked, carefully open each packet (beware of hot steam!). Place a slice of Swiss cheese on each burger and loosely re-close the foil. Let sit for 2–3 minutes until the cheese is melted and gooey.
7. Serve & Enjoy
For extra richness, you can add a small pat of butter to the hot potatoes just before serving. Serve the packets as-is or slide them onto a plate for a fancier presentation.
